consists of a metallic cap having a circular A rim or flange which iscrimped or fluted, a

layer of cork, and a layer of paraffin paper interposed between thelayer of cork and the cap`;'f=' H`hi`s ca is secured to the mouth of thebottlezby ben ing in the crimped portions of the fiange or rim so as toembrace a bead surround-ing the neck of the bottle. Owing to thedifficulty' of obtaining cork which is unperforated, .itfrequentlrhappens that caps are su plied in large numbers with corks that are deective in that they have small holes or v cracks which permit theleakage of the contents of the bottle, or throu h which the liql` uid orgas containedin the ottlema pass,

so as to oxidize or destroy the metalic cap and impair the quality ofthe contents of the bottle. Again, another difficulty has been foundwith the use of these caps in which the contents of the bottle may comein contact withthe cork, to wit,-that after a while the contents of thebottle contain numerous small 1pieces or specks of cork and dirtdeposite from the cork layer, and, especially where the bottle `containspure water, the

"water tastes corky and its commercial bottle, a thin commerciallysuccessful,

valueis destroyed.

Inone form of cap stopper in which a lockcap, it has been vpro sed tointroduce between the layer of costo and the mouth of the 'layer oftenacious. or ductile metal, but this form of stopper has not beenprobably owing to the difficulty of securing t e layer ofductile metalin the 'cap and of fastening the cap on the bottle after the layer hasbeen secured in it. I have found by experience that by emploing a sheetof ductile metal suclas chemica y pure block tin, aluminium or alloys ofThe commercial form of bottle stoppersl tin, in conjunction with a layerof elastic mate'rial such as cork, and a crimped cap, the bottle may beeffectively sealed and the contents thereof remain unim aired for a longtime even though the cork 1s defective. After numerous experiments, Ihave devised means for securing the layer of ductile 'metal in p'laee inthe cap by forming it with a bent rim or flange, and placing the disk soformed in the cap, with the flange or rim' `inserted-between the layerof cork and the cylindrical wall of the cap. When the parts areassembled, the lateral pressure of the cork against the rim or flange ofthe disk of'ductile metal serves to hold it in place so that'theStoppers ship ed in quantities, all without danger of the islocation ofthe disks. I have further found that, after the ca is secured to thebottle, the flange is cause( to ress even more tightly against thesurroun ing cylindrical wall of the cap so as to\securelyhold it againstlateral movement and prevent its dislocation when the cap is re noved.
